摘要金属环，特别是那些小环，在有机金属和配位化学领域发挥着重要的作用。它们被认为是金属促进或催化反应中的活性中间体，包括烯烃歧化反应和炔烃聚合反应。由于环应变较高，小的金属环很容易与不饱和化合物反应生成环应变较低的扩环产品。为了进一步了解小金属环中间体在催化反应和合成方法学中的重要性，综述了几种典型的三元、四元和五元金属环的扩环反应。
Abstract Metallacycles, especially those small rings, play an important role in the field of organometallic and coordination chemistry. They are considered as reactive intermediates in metal promoted or catalyzed reactions including olefin metathesis reactions and alkyne polymerization reactions. Due to the high ring strain, small metallacycles can easily react with unsaturated compounds to produce ring expansion products with lower ring strain. To further understand the importance of small metallacycle intermediates in the catalytic reactions and synthesis methodology, the ring expansion reactions of several typical three-, fourand five-membered metallacycles is summarize.
